Very interesting question. What evidence do we have of dukkha describing purely physical pain? I ask this because the Buddha did not overcome physical pain, right? So if dukkha can include physical pain, then the Buddha did not overcome dukkha.
There in SN 38.14, the 3 types are:
Dukkhadukkhatā,
saṅkhāradukkhatā,
vipariṇāmadukkhatā
Thanissaro translates them as:
the stressfulness of pain,
the stressfulness of fabrication,
the stressfulness of change
I’m not sure about the word ‘stress’. Nor translating dukkha as both ‘stress’ and ‘pain’ - it that really valid for the first one?
How about leaving ‘dukkha’ untranslated for the moment. So
vipariṇāmadukkhatā be more accurately classed as ‘the dukkha of changes for the worst’, or ‘the dukkha of disappointment’?. Because vipariṇāma doesn’t seem to be just the neutral term for ‘change’.
Then saṅkhāradukkhatā… I find ‘the stressfulness of fabrication’ to be a rather meaningless term if I look with ordinary English eyes. It leaves me confused and with no idea what is being meant.
How about:
‘the dukkha of mental imprints?’
or…
‘the dukkha of complexity’? (referring to the compounded nature, but ‘compounded’ doesn’t do it for smooth English).
or…
‘the dukkha of volitional mental activity’?
‘the dukkha of mental tendencies/inclinations’?
Or if we take it to refer to ‘mental fabrications’, to use Thanissaro’s term:
mental fabrication: feeling (feeling tones of pleasure, pain, or neither
pleasure nor pain) and perception (the mental labels applied to the
objects of the senses for the purpose of memory and recognition).
then how about:
‘the dukkha of feeling and of the mental process of perception’?
But that still leaves the mystery of dukkhadukkhatā.
But my point here really is, could perhaps all dukkha be emotional? Negative emotional experience resultant from 3) things changing for the worse/disappointment; 2) mental tendencies of mental processing, maybe also of feeling. And 1)… I’m not sure, maybe the negative emotional experience of negative emotions themselves? Or maybe this is really two meanings of dukkha, the second being physical pain, such that it means: ‘negative emotional experience resultant from physical pain’?
Also, sukha is qualitative emotionally positive experience, is it not? And since dukkha is the opposite of sukha, would we not expect dukkha also to be emotional - positive emotional state?
I just can’t see how dukkha can include physical pain, since the Buddha had a chronic painful back, and died in pain also. But if anyone has any evidence of dukkha meaning physical pain (and no merely emotional pain in response to physical pain), then please share about it here!
